Perl is a flexible, open-source, and widely accessible scripting language used by systems administrators and others to automate their daily tasks. "Perl Power!: The Comprehensive Guide" will cover every aspect of the most up-to-date version of Perl including scalar data, lists, arrays, hashes, subroutines, files, directories, strings, and much more. Technical topics are explained clearly and concisely and end-of-chapter projects encourage the reader to program on their own. A detailed table of contents and a complete, well-organized index make this book a great reference tool. All code used in the book will be available for download on the companion website.
